Link for adding a new post

Hi people! I was wondering if I can do what I need to do. When you create a Post (add command inside a blog) you are ask first which type to ask and a name. You can put "zaraza post" as name and type "Post". Then you go to another page (second one) where you put all the information of the post (included the name again ("zaraza post" in this case)). Suppose you have a pier site and the final user can add posts (not create the blogs, just post). I would really love to have a link that says "click here to post" or something like that. In this case, the type we ALWAYS be "Post". And as the title is asked again in the second page, I ask: is there a way that from a simple link I simulate an add of a Post type and this goes directly to the second page ? In other words...if there is only one "type" option, can I skip this step and go to the seconds step ? I think this email was very confusing, sorry. Thanks in advance, Mariano
